WebApr 14, 2024 · 1.3 The Paraxial Wave Equation. This section loosely follows (Siegman 1986, Sects. 16.1 and 16.2). The Sommerfeld radiation condition, Eq. 3.14, requires the scalar field \(\tilde{\psi }\) to fall like a spherical wave for the radius approaching infinity. Thus, a generic spherical wave is an appropriate choice for the wave field.
